Article Synopsis
  • Integrated pest management (IPM) is a sustainable approach to pest control, but adoption rates are low among citrus farmers in Iran; this study explores the factors influencing this behavior using protection motivation theory (PMT).
  • Farmers showed limited usage of IPM practices, primarily focusing on monitoring, with perceived severity of chemical controls and efficacy of IPM positively influencing their adoption, while costs and barriers hindered it.
  • The PMT model provides insightful understanding of IPM practice adoption, highlighting that the perceived risks of chemical usage strongly motivate adoption, while perceived costs significantly deter it.

Despite considerable differences in cropping systems around the globe, chemical weed control is a key tool in conventional agroecosystems, which has led to an increase in herbicide resistance. Although mutations causing resistance are thought to have an adaptation cost in resistant plants compared to the susceptible ones under herbicide-free conditions, such cost may not always express or will express under certain ecological conditions. To ensure that herbicides will keep going as viable instruments in agricultural production, strategies to minimize resistance are needed.

Chlorpyrifos (CP) and profenofos (PF) are organophosphate pesticides (OPs) widely used in agriculture and are noxious to both fauna and flora. The presented work was designed to attenuate the toxicity of both pesticides in the growth parameters of a cotton crop by applying plant growth-promoting rhizobacteria (PGPR), namely Pseudomonas aeruginosa PM36 and Bacillus sp. PM37.

Background: Herbicides are the major method of weed control in most conventional cropping systems, but what affects farmers' intention to use herbicides has not been studied extensively. This study examined herbicide use among cereal farmers of northern Greece and tested for the first time whether the theory of planned behavior (TPB) can explain farmers' behavior in the adoption of herbicide use.

Results: Most farmers showed favorable attitudes towards herbicide use (71.

Public acceptance of treated sewage (TS) reuse in agriculture is a key element in successful implementation of TS reuse projects, but relevant research on the topic is limited. This study examined public willingness to accept (WTA) and willingness to pay (WTP) for agricultural products derived by irrigation with TS in Lorestan province, Iran, applying the contingent valuation (CV) method. The agricultural products determined for the study included corn, peaches, apricots, and plums, while TS was introduced in three qualities [Q1, complete TS treatment (i.

Numerous studies have examined how farmers are involved and behave in the use of pesticides, but what drives farmers' intention to diminish pesticide applications is mostly unknown. This study explored farmers' intention to minimize pesticide use, through the theory of planned behavior (TPB) and an adjusted form of the TPB, with perceived risk of loss as an additional variable to the original model. On a scale from 1 to 5, intention to reduce pesticide use had the lowest score of all variables (2.

Background: Labels are the first source of information for the safe use of pesticides, but farmers rarely read labels before pesticide use. Using data from a sample of 300 orchard farmers in Meshginshar County, Iran, this study examined farmers' intention and behavior in reading and using risk information displayed on pesticide labels, using the theory of planned behavior (TPB).

Results: Only 26% of the respondents mentioned that they read pesticide labels.

Inappropriate handling of pesticides in agriculture poses a major risk to the environment and human health, but factors affecting farmers' behavior are diverse and often unclear. The present study examined farmers' behavior in safe pesticide use (disposal of spray solution leftovers, places for washing sprayers, disposal of rinsates, and use of personal protective equipment) in Ardabil Province, Iran by applying the well-known theory of planned behavior, which states that attitudes, subjective norms, and perceived behavioral control of individuals shape intention and engagement in a specific behavior. Almost 30% of the farmers threw pesticide spray solution leftovers away, while the remaining farmers kept it for next spraying.

Numerous studies have been carried out on pesticide handling practices in agriculture, but drivers of farmers' intentions to use pesticides are not well documented. The main purpose of this study was to explore farmers' intention to use pesticides in agriculture, based on an expanded version of the theory of planned behavior (TPB), with knowledge about pesticides and moral norms as additional constructs in the original TPB model. A sample of 400 cereal farmers of irrigated farmlands of Moghan plain, Iran was selected using multistage cluster sampling.

Article Synopsis
  • Women in Pakistan, especially young and married, are the primary cotton pickers but often lack awareness of pesticide risks and personal protective methods, resulting in health issues like skin and eye injuries, headaches, and fevers.
  • More than half of the surveyed workers did not use protective gear, with the majority using only mufflers or scarves, and factors like education and experience were positively linked to the use of protective measures.
  • The study highlights a need for greater education and training on safety practices for women cotton pickers to minimize health risks and associated medical costs from pesticide exposure.

The accumulation of trace elements in wastewater-irrigated soils may introduce them to the food chain and therefore can threaten human health. The present study investigated the accumulation, translocation factor, and health risk potential of cadmium (Cd) in a soil-wheat system irrigated with treated wastewater compared with a reference soil (irrigated with fresh water). All treated wastewater-irrigated soils showed significantly higher levels of electrical conductivity (EC) than that of reference soil by 75-143%.

Insect physiology is affected by the presence of toxins in the surrounding environment of insects as well as their food sources. The objective of this study was to determine the effect of heavy metal exposure to two low concentrations (50 μg/g and 150 μg/g) of lead (Pb) and zinc (Zn) through artificial diet to the larvae on biological parameters of Asian armyworm (Spodoptera litura Fabricius) (Lepidoptera: Noctuidae). Both Pb and Zn, even at low concentrations, had relatively high toxic effects on S.

Integrated pest management (IPM) has been promoted as an environmentally friendly pest control approach, but its adoption by farmers, particularly in developing countries, is low. The main purpose of the current study was to examine factors affecting the intention of farmers to use IPM practices in Iran. The research model was developed using the Theory of Planned Behavior (TPB) and the Norm Activation Model (NAM) and was empirically tested using data obtained from structured interviews with 327 tomato producers in Zanjan Province in northwestern Iran.
